Using Donor Stem Cells and Alemtuzumab to Prevent Organ Rejection in Kidney Transplant Patients

Completed · Phase 1/Phase 2

Conditions studied: Kidney Transplantation, Kidney Disease, Kidney Failure

In brief

Alemtuzumab is a man-made antibody used to treat certain blood disorders. This study will evaluate treatment of kidney transplant recipients with alemtuzumab and other immune system suppressing medications with or without infusions of bone marrow stem cells from the kidney donor. The purpose of this study is to find out which strategy is more effective in preventing organ rejection and maintaining patient health.
